To acquaint yourself with students at a remote site consider scheduling a point-to-point video conference. In addition to getting to know your students, your students will then know how they can technically communicate with you during the course.
Select the video tool that might support the easiest and best connection. Note that students will probably need something on their desktop/mobile device.
Options: Google hangouts, Clearsea, Scopia, Skype.
Create and share with students your meeting plan. Some questions you might consider asking:
Is this the first class you have taken over video conferencing?
If so what are your expectations? concerns?
If you have taken a class before what were positives or ways that might have improved the class?
What are your favorite subjects?
Why are you taking this class over VC?
What subject interests you most in school?
Do you have some extra-curricular areas you are involved with?
As a followup to the meeting, ask to share the benefits of the conference (ie administration, ESU, other DL teachers)
Might this be used for a Parent/Teacher conference?
